Don, I noticed that -- for revenues, anyway -- the link for "
ebay 'Sold' values" brings up "completed" listings, not "sold" listings. This means that a lot of unsold items are included (many more than actual sold items), with asking prices that are essentially useless because they attracted no buyers, even if they aren't ridiculously overstated. Nonetheless, the Popup Stamp Tool is another great resource that you're providing to collectors!
